3 Claims.

My present invention relates to a combined diversion and hot-cold control device.

More particularly, my invention relates to a fixture applicable to be connected with pipe lines serving heated and unheated water, and having appropriate valves for controlling the relative quantities of such heated and unheated water, and passage means Within or directly associated with the casing and provided with valve means for controlling dually the direction and the extent of the flow of the inter-mixed heated and un. heated water, to either of two appropriate locations, such as tub and shower, tub and basin, shower and basin, etc., with which the fixture is piped.

The most preferred forms of my invention embody a casing, nipples and chambers extending into the casing for the respective hot and cold pipe lines, valve seats respectively disposed within the casing for such chambers, movable valve members, preferably appropriately designated hot and cold which cooperate with such valve seats for the control of inflow of the heated and unheated water, suitable means for eiectively intermixing the heated and unheated water with-'-- in the interior of the casing, passage means for connection to the lines of piping leading to two diversified locations, such passage means having port means communicating with the interior of y the casing, and valve means for such passage means provided with a movable valve member for dually controlling the direction of diversion of the ow of the'intermixed heated and unheated water and the extent of such ilow.

The invention, as is apparent, is not restricted to the control of water nor to the control of two streams of relatively heated water, but is applicable to the admixing of any two streams of liquid and the control of the divergent ow and the extent of such divergent now.

An advantageous feature of certain types of embodiments of my invention resides in the combination with the casing into which the respective "hot and icold water, or other two uids, now, of outflow passage means arranged to be connected to piping leading to two locations or use,

and valve means for such outflow passage means affording, firstly, communication between the in terior of the casing and the outflow passage means, secondly to select the terminus of the now, and thirdly the extent of such diverted now.

Further features and objects of the invention will be more fully understood from the following detail description andthe accompanying drawings, in which Fig. 1 is a front elevation of a preferred form Yof my invention, illustrated as adaptable to a hot-cold-shower-t fixture;

Fig. 2 is a vertical sectional elevation on the broken section line 2-2 of Fig. 1;

Fig. 3 is a. vertical section online 3-3 of Fig. 2; Fig. 4 is a detail sectional elevation on line 'fa-4 of Fig. 2; and

Fig. 5 is a detail sectional elevation on line 5-5 of Fig. 2.

Referring to the illustrated preferred form of my invention, the casing I0 may be of any sintable coniiguration, that illustrated in Figs. 1 and 3, being generally triangular.

At the lower end, as appears in Figs. 1, 2 and 3, 15 is provided the nipple portion II for connection with piping supplying heated, that is hot, water, and the nipple portion I2 for connection with piping for supplying unheated, that is cold, water. The nipples II and I2 are indicated as 20 provided with threading and therefore anording y connection with piping -by threaded pipe fittings;

however, such connection may be by sweat joint or any other form of present day or other approved type of connection. The nipple portions 25 I l, I2 communicate with the respective chambers I3, I4, in turn terminating at their valve seats I5, I6, respectively, see Figs. 2 and 3.

Referring to Figs. 2 and 3, the chamber I3 communicates through the opening of its valve seat 30 I5 with its outflow chamber I1, preferably provided with oppositely directed outflow ports I'la, Ilb, or equivalent, leading into the interior of the casing I0. The control of the outow through the opening of the valve seat I5 is had by any suit- 35 able valve means. As illustrated in Fig. 2, such valve means comprises the movable valve member I8 carried by the rotatable stem I9, secured as by a screw 20 to its operating handle 2l.

Correspondingly, the outow chamber com- 40 municating through the opening of the valve seat I6 of the chamber Ill is provided with suitable ports I8a., lab, see Fig. 3, preferably projecting the discharge in oppositely directed streams, thus cooperating with the oppositely directed ports 45 I'la and Ilb to effectively intermix the two streams within the casing l0. For such purpose, it will be observed, the ports Ilb and Iilb are directed in a downward direction, and the ports Ila and Ilia are directed in a general upward 50 direction, thus precluding any stratiiication of unheated water in the lower portion of the casing and heated water in the upper portion of the casing.

Directly associated with the casing I0, and 55 preferably a lmitary part therewith, I provide passage means 22 and a valve 23 therefor, such passage means communicating, as through a port 24, see Fig. 2, specifically through the movable valve member 23a, with the interior of the casing l0. The passage means 22 is further provided with extensions 25, 26, for connection respectively with piping leading to any two appropriate locations of discharge or use, such as one piping leading to a shower and the other piping leading to a tub, for which particular diverting use the xture illustrated in Fig. 1 bears the legends "Shower" and Tub.

The terminalor nipple portion 25a of the extension 25 and the nipple portion 26a of the extension 26 may be threaded, as indicated in Figs. 1 and 3, or may be connected to the piping by sweat joint or any other suitable form of connection.

The stem 23a of the diverting valve 23 is provided with any suitable form of operating handle 21, desirably to have an index portion 21a, see Fig. 1., and thus indicate the direction of diversion effected by the valve 23 at its `various positions of setting. For such or other purpose, the discharge port 23h of thediverting valve 23, see Figs. 2 and 3, is arranged in operative position to correspond to the index portion 21a. In the position illustrated in Figs. 2 and 3, the discharge port 23h communicates with the extension 25 of the passage means 22, thus directing the ow of the uid from the interior of the casing I0 into the piping leading, in this instance, to the shower, the path of ow being specifically through the iniiow port 24, thence through the body of hollow movable valve member 23, thence through the discharge'port 23b, into and through the extension 25 of passage means 22, andthus into the piping leading to the shower.

It will be further observed that rotationof the movable valve member 23 continued from its position shown in Figs. 2 and 3 effects more and more the restriction of the extentof eective communication of its discharge port 23h with the extension 25 of the passage means 22, thus restricting the flow to any desired extent. Correspondingly, upon rotating the operating handle 21 to move its index portion 21a, say one hundred and eighty angular degrees from its position as shown in Fig. l, the discharge port 23b is brought into more and more e`ective communication with the extension 26 of the passage means 22, thus diverting the water to corresponding extent of iiow to the Tub.

As illustrated inthe drawings, the discharge port 23h is preferably of a range of angular opening to provide at ay setting iiow, and of regulated extent, exclusively into either of the two extensions and the corresponding location of ultimate discharge.

It will be observed that the general triangular conguration of the casing I0, coupled with the location of the diverting valve 23 toward the upper apex of such triangular outline, see Fig. 3, the Vdischarges of the hot and the cold valves being located at the base of such triangular configuration on opposing sides of the port 24, and at substantially equal distance from the diverting valve, is eiective for insuring complete intermixing of the two ows into the easing and substantial uniformity of temperature through the port 24, for any given settings ofthe inflow valves I 5 and I 6 and the outow valve 23.

Aa appears from the above, thespecific construction and the material of the detail parts of my invention may be selected as preferred and pursuant to the requirements of commercial operation 4conditions well understood by those skilled in the art. Desirably, the casing and the valve and other parts of embodiments of my invention are formed of metal, either cast to desired forms or of suitably shaped wrought metal or equivalent.

To afford convenience of assembly, and also 1 for disassembly in the circumstance of repair, inspection or the like, it is convenient to provide a face plate I 0a of stamped or shaped wrought metal, separate from the casing proper I0, in which form of manufacture the front face por- 1 tion Illb of the casing proper I0 may be provided with nipple formations Illc, |0c for the respective inow valves I6, Il and a similar nipple formation ltd for the outflow or diversion valve 23,- a gasket 30 being interposed between each 2 movable valve stem Within its nipple formation, and locked by a washer or lock-nut 3| or equivalent, as is indicated in Fig. 5 with respect to the outow or diversion valve 23.

Such front plate Illa may desirably be stamped 2,1 with the legends Hot, Cold", Shower and Tub, or equivalent designations.

Coacting with such front plate Illa, I may provide for each movable valve stem a hollow boss 32 having an outer terminal portion 32' of 31 y square or otherpolygonal contour for securement thereto by a set screw 20 of the respective operating handles (2l, 2|, for the two inow valves and 21 of the outow or diversion valve), each handle being provided with a correspondingly 34 contoured opening, and* each boss 32 has an inner' terminal portion 32a of squared or other polygonal contour, receiving a correspondingly contoured outer stem portion, see 23a. Fig. 4, of the movable valve stem 23a, whereby upon grasping 4U and turning an operating handle, the torque is transmitted through the stated respective mating polygonally contoured parts, the set screw 20 serving merely -to-hold the stated puts in operative relation.

Whereas I have described my invention by reference to specic forms thereof, it will be understood that many changes and modications may be made without ,departing from the. spirit of l the invention.
